CORE-946 + CORE-945: headsampling tracestate + dry run

[natyharary]

What this PR does / why we need it:

1. Adds the tracestate attribute (w3c-coded), mirroring the nodejs instrumentation.

Tracestate spec:
https://github.com/odigos-io/odigos/tree/main/collector/processors/odigostracestateprocessor

2. This PR also adds the support for the dry run config, which not only makes traces be recorded irregardless of the sampling rule (hence the "dry" run) but also adds an indication on the tracestate.
3. Bonus: adds ruff (linter) + ty (typing linter) support with pyproject, CI and git pre-commit hooks.

Changelog entry: Does this PR introduce a user-facing bug fix, feature, dependency update, or breaking change??
